Sanyo Denki stepper specs

Hi all,

I found a couple old Step-Syn stepping motors from Sanyo Denki. The label says Type 103-89200-0240, DC 5.3V, 3.4A, 1.8 deg/step. These are 4 inches dia and 6 inches long with 6 wires coming out from the back. Any clue on their torque rating? I am planning to use them on my BP clone once I acquire the ball screws for it.
